Specification of Letters Patent.

Application filed December 28, 1907. Serial No. 408,365.

To all whom "it may concern:

Be it known that I, KARL Tnroninixs, ongineer, a subject of the King of \Vi'irtembcrg, and resident of Salzdet'furth, near Ilildes heim, German Empire, have invented ccrtain new and useful Improvements in Elevating. Appliances for Use in. Mines and the Like, of which the following is an exact.

specification.

This invention relates to the elevating appliances used in mines and the like. In such elevating appliances it is customary to pass the elevating rope or ropes from the winding engines over a number of pulleys mounted on an. elevated platform. In such arranga ments it has been necessary to effect the adjustmen-t of the height or depth to which the cage, bogie or other receptacle or article was to be raised or lowered by means of the 'winding engine. This adj ustmcnt has proved exceedingly difficult in the case of deep shafts where long. cables are necessarily employed. Thus the stretching of the cable under various loads could not be judged by the operator at the winding engine, and considerable delay was sometimes caused by the difficulty of bringing the cage or the like to a standstill in exactly the correct position.

The object of this invention is to provide means for enabling this exact adjustment to be effected Without employing the winding engine.

To this end the invention consists in providing the elevated pulleys over which the rope or ropes pass with means for moving the same as desired to effect the required fine adjustment. It is also preferable to provide means 'for controlling the elevating or lowering of the pulleys from a distance.

In carrying this invention into effect any convenient means may be employed for raising or lowering the elevated pulleys over 3 which the ropes pass.

Referring now to the accompanying d rawings Figure 1 is an end view and Fig. 2 is a diagrammatic side view of an elevating plant for use in mines according to this invention, Figs. 3 and at are views similar to Figs. 1 and 2 showing the range of control by means of the movable pulleys, Fig. 5 is an enlarged detail of the hydraulic device which I may employ for raising and lowering the pulleys, Fig. 6 is an elevation and Fig. 7 is a plan of a device for raising the block by means of a wedge, Fig. 8 is an elevation and Fig. 9 is a plan of a device for raising or lowj cring the pulley by means of a pivoted l girder.

j In carrying the invention into effect according to the form illustrated in Figs. l-4- the ropes pass from the winding engine a over pullcysf and j" supported on an upper platform. The pulleys arc journaled in brackets 71 supported on elevating devices Ir and hereinafter more fully described with reference to Fig. The ropes connect with cages or bogies I) and b which are moved between the ground level and various platforms in the mine such as a. By means of the winding engine a the cage 7) for example is lowered to the position shown in the lower part of Fig. 2 that is to distance a from the level of the 5 platform 0. By bringing the device 7; into operation the pullcyj" is moved downward through a distance which is approximately 1f the rope is assumed to descend practically vertically from the elevated pulleys to the winding engine. In this way the cage or bogie I) is brought to the level of the platform c. Meanwhile the bogie or cage 1) has by means of the winding engine been brought into the position shown in Fig. 1, that is to say, at aalistancc m from the ground level (Z, the pulley raising device 76 is then brought into operation to raise the p ulleyftln'ough a m distance r) by wluch means the bogie Z) is brought to the level of the ground (Z as shown in Fig.

In carrying this invention into effect according to the particular form shown in Fig. 5 the raising of the pulleys f andf is eli ected by hydraulic moans, that is to say, the pulley f is journalcd in the block It which is supported by means of hydraulic cylinders 1) p to which there lead pipes s from a pump 15. The pipes s are provided with cocks such as s placed about or near the level 01' the ground (Z or the various platforms 0 in the mine. In the form shown adjustment of the height of the pulleys f, f is efiectcd by operating the pump t at the landing stage of the In Fig. 5 the device is illustrated in side view and it will of course be understood that two hydraulic cylinders p and corresponding rams g are also provided on the other side of the pulleyf as indicated in the diagrammatic Figs. 1 and 3.

According to the example shown in Figs. 6 and 7 I employ an electric motor for effecting the raising of the pulleys f and f. It will be understood, however, that any convenient motor may be employed. According to the form shown in Figs. 6 and 7 the blocks h in which the pulleys are journaled rest in an inclined position on wedges 2 connected by rods 1 with a nut to. With this nut there engages a screwed rod 12, adapted to be turned by means of the electric motor a. The wedges .2 rest on plates 0 provided with angle plates 0 against which the blocks 7/ rest. It will be seen that by these means when the motor a is rotated in one or the other direction the wedge blocks 2 are moved toward or away from the plate 0 and the raising and lowering of the bearing blocks 7L is eil'ected. In this case the motor a is controlled by switches placed at the desired positions.

According to the form of this invention shown in Figs. 8 and 9 the bearing blocks 7L2 are mounted on girders A pivoted at A. These girders A are adapted to be raised and lowered by means of a block and tackle B, the operating chain of which is carried to the various parts at which it is necessary to eii'ect the adjustment of the cage.

I claim 1. An elevator for use in mines and the like having in combination with elevated pul leys, a carrying cable passing over said pulleys and a winding engine, a cage carried by the cable and means for bringing said cage to 1 a stand still at the correct position independently of the winding engine comprising bearings for the elevated pulleys and means for moving said bearings up or down as required.

2. An elevator for use in mines and the like having in combination with elevated pulleys, a carrying cable passing over said pulleys and a winding engine, a cage carried by the cable and means for bringing said cage to a stand still at the correct position independently of the winding engine comprising bearings for the elevated pulleys and means operable from the landing point of the cage for moving said bearings up or down as required.

3. An elevator for use in mines and the like having in combination with elevated pul leys, a carrying cable passing over said pulleys and winding engine, a cage carried by the cable and means for bringing said cage to a stand still at the correct position independently of the winding engine comprising bearings for the elevated pulleys, hydraulic rains supporting said bearings and means for supplying operating fluid to said rams from the landing point of the cage.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
